My current pair of earbuds is dieing and I'm looking for a new portable solution. My main source will be a Galaxy Note II with lossless or 320kbps MP3s. I would prefer not to use an amp. I listen to mainly trance/house/other electronica, but do listen to some rock and pop. I would say focus on the electronica sound the most. I have a budget of around $100 dollars (this will be a birthday gift for me), but would not object to throwing in another $50 or so if needed. Isolation/noise cancelling would be a plus as well. If I could order them from Amazon that would also be a plus because I would like to overnight them for a flight this weekend.
SE-215 would be be a nice choice if you want lots of isolation. It's a little bassy, but it doesn't lack mid or highs either. Sounds like an 100$ earphone but the isolation feels like its a lot more than 100$.
